"In May 2010, it was recognized by the Ministry of Science and Technology, the Ministry of Environmental Protection, the Ministry of Commerce and the General Administration of Quality Supervision, Inspection and Quarantine as a "National Key New Product".
Second, microbial generator
Microbial generator is mainly based on biological purification and hydrodynamic principles, the use of microorganisms in the process of life activities in the wastewater soluble organic matter and some insoluble organic matter effectively removed, advanced technology, stable performance, safe to use, especially suitable for a variety of wastewater (polluted) water treatment and micro-pollution management has the following advantages:
First, the equipment adopts three-stage occurrence, alternate operation, level by level derivation, logarithmic growth technology, resulting in the generator to produce microbial density up to 1.8 × 1020CFU/ml, high-density microorganisms released into the biochemical pool, the pool biomass rapidly increased to 2.0 × 104mg/L or more, can be sewage pollutants in the complete decomposition of CO2 and H2O, so that the sewage is purified. Purification.
Secondly, this equipment is an ideal biological treatment equipment for sewage, which can generate microorganisms of different populations, genera, temperatures, and sewage treatment needs according to different kinds of wastewater treatment needs, especially suitable for urban sewage, rural sewage, medical sewage, industrial wastewater, livestock and poultry wastewater, high salt wastewater, high ammonia wastewater, toxic and hazardous wastewater, heavy metal wastewater and other wastewater. It is especially suitable for the treatment of urban sewage, rural sewage, medical sewage, industrial wastewater, livestock and poultry wastewater, high salt wastewater, high ammonia nitrogen wastewater, toxic wastewater, harmful wastewater, heavy metal wastewater, waste leachate and other wastewater.
The equipment can also be directly with the contact oxidation method, AB method, A/O method, oxidation ditch, SBR and other old wastewater treatment works, in neither change the wastewater treatment process, nor change the conditions of civil engineering, to realize the upgrading and expansion of wastewater treatment, sludge reduction, denitrification and removal of phosphorus, water reuse and other purposes. The equipment can also be used in landscape, river, lake, river, saltwater lake, bay, land and other fields to remove micro-pollution and protect the public **** environment.
Third, the microbial generator produces a high density of advantageous microbial flora, can quickly eat off the pollutants and sludge in the sewage, and does not produce odor, without sludge dewatering machine, sludge conveyor, sludge cake outgoing car, exhaust gas treatment equipment and high-power blower aeration equipment, and the traditional method of comparing the energy consumption of the activated sludge method of 1/8, the investment in equipment can be saved by seventy percent, but also in the Shallow pool operation, thereby reducing the size of the sewage treatment tank, shallow depth, greatly reducing the cost of an investment and long-term management costs.
Fourth, the equipment produces a high density of microbial flora through the jet stream into the treatment pool, can quickly reduce biological oxygen consumption in sewage (BOD), chemical oxygen demand (COD) and suspended solids (TSS), and has a strong function of denitrification and removal of phosphorus, but also in a very short period of time so that the five types of water into three or more, 7 days to eliminate the sewage odor, 10 days to eat the sewage in the About 50% of the sludge in the sewage in 10 days, degradation of 20% of the BOD every day, 10-15 days to achieve discharge or reuse of water.
Using this equipment to treat sewage without the worry of sludge expansion, but also not subject to the age limitations of the operator's education, easy to manage, safe and reliable.
Fifth, with the increasing incidence of high-density microbial flora, biological oxygen consumption (BOD) in the sewage is also less and less, a large number of microorganisms due to the lack of BOD and the loss of energy to survive self-extinction into carbon dioxide and water, not self-extinguishing microorganisms can also become the bait for fish and zooplankton, which will form a benign ecological process of treatment and purification, there is no odor, does not produce sludge, no secondary pollution, to create a green environment. The second pollution, to create a green environment.
Six, the use of traditional biochemical method of sewage treatment, affected by the climate and water temperature changes, when the temperature decreases every 10 degrees, the microbial enzymatic reaction rate is reduced by 1-2 times, the climate leads to microbial activity is insufficient, resulting in poor sewage treatment, not only threatened by the northern sewage treatment plants, for the southern winter sewage treatment plant is also a severe Jun test, Guizhou Great Wall Environmental Protection Science and Technology Co. Ltd. production of patented products biological generator completely solve this problem, the generator produces a high concentration of microbial flora released into the aeration pool, its biomass signaling rate of 2.0 × 104mg / L or more, so that the biological concentration of the aeration pool than the activated sludge to increase by 10 times, to fill the water temperature due to low biomass caused by low water temperatures, the sewage treatment effect of the poor technical problems.
Seven, the traditional biochemical treatment of high concentration, high ammonia nitrogen, high salt, toxic, heavy metal wastewater, due to the microorganisms in these wastewater is less viable, the number of small, resulting in poor quality of effluent after sewage treatment, the effect is unstable, and difficult to meet the discharge standards. Microbial generator in a unique way to completely solve this problem, the generator can produce 1.8 × 1020CFU / ml above the high concentration of microbial flora constantly sent to the aeration tank, compared with other sewage treatment to improve the biomass of more than 10 times, the powerful microbial flora to accelerate the degradation of sewage pollutants in the degradation and digestion, while aeration and oxygen supply significantly accelerates the pollutants are broken down into CO2 and H2O, nitrate, sulfate become nutrients for microbial growth, so that the microorganisms and further derivation, even by the cold, low temperature, shock load, and high concentration, high ammonia nitrogen, high salt, toxicity, heavy metal inhibition, but also can not stop the group of microorganisms competing for the front and back of the microorganisms, the formation of a strong lineup of wastewater treatment, and then the degradation and digestion of wastewater pollutants, and eventually Realize the wastewater discharge or water reuse.
